[en] The purpose of the study was to determine whether Sodium hypochlorith and Glutaraldehyde would be effective for the surface disinfection of contaminated radiographic film pockets with saliva. The following results were as obtained. 1. Proper times for surface disinfection of 2.0% Glutaraldehyde and 3.5% Sodium hypochlorite were 60 seconds. 2. When films were immersed in 2% Glutaraldehyde solution for 1 minute, bacterial colonies were present in 24 cases (80%). 3. When films were immersed in 3.5% Sodium hypochlorite solution for 1 minute, bacterial colonies were absent in 24 cases (83.3%). 4. Differences of effectiveness on surface disinfection between 2% Glutaraldehyde and 3.5% Sodium hypochlorite were statistically significant.
[en] In view of its prevalence in the Far East area, a more detailed knowledge on the hookworm infection is one of the very important medical problem. The present study was aimed to determine the infectivity of the artificially hatched ancylosotma duodenale larvae in man after its oral administration, evaluate the clinical symptomatology of such infection, determine the date of first appearance of ova in the stool, calculate the blood loss per worm per day, assess the relation-ships between the ova count, infectivity (worm load), blood loss and severity of anemia. An erythrokinetic study was also done to analyse the characteristics of hookworm anemia by means of 59Fe and 51Cr.
[en] The intravenous pyelograms of 126 cases of ureteral stones were analysed for study on charges in size, renocortical index (RCI) and function of the affected kidney. The following results were obtained. The following results were obtained. 1. The size of affected kidney was increased in 45% of cases and decreased in 40% of cases. 2. The affected kidney showed an elevated RCI value as compared to the normal side. The mean value of RCI of the affected kidneys was 0.44 and normal kidneys was 0.35. 3. The cases of upper ureteral stones most frequently showed urinary stasis. The incidence of urinary stasis; hydronephrosis 61%, hydroureter 48%, nonvisualization 10%, and combined hydronephrosis and hydroureter in 54% of the all cases
[en] To determine ultrasonographic findings of mumps epididymo-orchitis to differentiate from other causes of epididymo-orchitis. We retrospectively analyzed the sonographic findings of 11 cases of mumps epididymo-orchitis in 10 patients. US findings were analyzed in terms of echogenicity, size, hydrocele, and calcification. The age of patients ranged from 12 to 27 years (average 16.6 years). A total of 11 lesions were involved testis : 2 lesions were located in left, 7 lesions in right, and bilaterally inone patient. Sonographic findings consisted of diffusely enlarged homogenous hypoechoic in 6 cases, diffusely enlarged in homogenous hypoechoic in 3 cases, and diffusely enlarged isoechoic testis in 2 cases. A total of 7 cases were involved epididymis : 5 cases were located in the head, and 2 in the tail. The sonographic finding of epididymitis was enlarged epididymis with heterogeneous hypoechoic pattern. The hydroceles were also seen in 5 cases. It is difficult to differentiate mumps epidydimo-orchitis from other infectiou sepididymo-orchitis only on the basis of ultrasonographic findings, but the clinical history of mumps can be helpful in diagnosis of this disease
[en] To determine the role of high-resolution sonography in the early diagnosis of experimentally induced clonorchiasis in rabbits. We performed sonographic examination weekly in 22 lightly-infected rabbits (10 rabbits infected with 10 metacercariae, 6 rabbits infected with 20 metacercariae, and 6 rabbits infected with 40 metacercariae), and 10 heavily-infected rabbits (500 metacercariae). The sonographic criterion of diagnosis with dilatation of the intrahepatic ducts. We sacrificed lightly-infected rabbits and counted numbers of adult worms of clonorchis sinensis 9 weeks after infection. Sonographic abnormalities were found 3 weeks after infection in 2 lightly-infected rabbits and 5 heavily-infected rabbits. On sonography at 9 weeks after infection, we observed dilatation of the intrahepatic ducts in 11 (65%) of 17 lightly-infected rabbits and all of 10 heavily-infected rabbits. High-resolution sonography is very useful in early diagnosis of rabbits clonorchiasis.
[en] Three cases of florid osseous dysplasia of the jaw were investigated. Radiographs showed sclerotic, globular and ground glass opacities throughout the jaws. Two cases were asymptomatic but one case failed to heal following extraction of the mandibular molar and infection complicated the disease. These cases appear to represent the most exuberant manifestations of this reactive benign fibro-osseous lesion of the jaws.
[en] The purpose of this study is to prevent nosocomial infection in patients through contact of radiographic cassettes. Data were collected from radiographers working in 29 university hospitals in Seoul in February and March 2001. Radiographic cassettes were disinfected daily in 5 hospitals, weekly in 4 hospitals, monthly in 5 hospitals, bimonthly in 1 hospital and once every three months in another hospital. 12 other hospitals do not practice regular disinfections of radiographic cassettes. Gauze soaked in disinfectant solution is used in 7 hospitals while 11 hospitals used cotton and cloth soaked in disinfectant solution to clean the radiographic cassettes. 26 hospitals used 99% alcohol based disinfectant solutions while 3 hospitals used 75% alcohol based disinfectant, 26 hospitals use of intercourse cassettes outpatients and in patients. In 26 hospitals, all patients shared the same set of radiographic cassettes used in the hospitals, or in 26 hospitals, separate sets of radiographic cassettes are used for outpatients and inpatients. Separate sets of cassettes are used for ICU and inpatients in 6 others hospitals. 23 hospitals used the same sets of radiographic cassettes for all their patients. radiographic cassettes are cleaned in wash area in the study room of the radiographic department in 17 hospitals. 12 other hospitals do not have designated cleaning areas for the cassettes. All radiographers practiced hands washing with soap. All 29 hospitals surveyed have infection control committee. However, only 9 out of the 29 hospitals surveyed provided Infection · disinfections control education to radiographers. Only 3 hospitals have radiographers sitting in the infection control committee. Infection management education is conducted in 63 hospitals annually, twice a year in 1 hospital and once every 3 months in 2 hospitals
[en] There have been report on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n=11), influenza 8(n=2) virus infections. The mean age of the patients was 23 months. Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), lobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases(19%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. The major radiologic features in viral lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections
[en] To evaluate the results and complications of the step tip type and split tip type tunneled hemodialysis catheters. Between March 2008 and December 2008, a total of 147 tunneled hemodialysis catheters of step tip (n=89) and split tip (n=58) type were placed in 126 patients to perform hemodialysis. We evaluated the number of catheterization days, as well as complications with respect to catheter tip types. A tunneled hemodialysis catheter was placed successfully in all cases. The duration of catheterization ranged from 7 to 180 days (mean 68, total catheter days: 10,504 days). A significantly higher complication rate was observed in the step tip type (n=23) as compared to the split tip type (n=4) (p=0.004), especially due to catheter dysfunction and catheter laceration. Five cases of catheter-related infection (3.4%, 0.48/1000 catheter days) were observed. Placement of the tunneled hemodialysis catheter of step tip type and spit tip type were performed safely. However, the split tip type is more useful because of the greater rate of complication in step tip type
[en] Congenital tuberculosis is an infection that is established in the fetus by hematogenous spread or by the aspiration or inhalation of infected amniotic fluid either before or during labor. The diagnosis can be confirmed only if both the tuberculous nature of the lesion and the antenatal origin of the infection can be proved. The authors analyzed roentgen findings of two cases of pulmonary tuberculosis, thought to be congential; 1. Diffuse distribution of nodular densities and some confluent densities were seen in the entire lungs in the initial film. The pulmonary markings were decreased in some degree. 2. Air bronchogram was noted. 3. Hepatosplenomegaly was associated.
